To all whom it may concern Be it known that we, VVILLIAMB. MoKnnN, J12, and'BARTrIoLoMnw JULLEN, citizens of the United States,-residing-at Omaha, in

the county of Douglas and State of Nehave invented certain new and use- Oar-Hea-ters, of which the following is a full, clear, and-exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates .to car. heaters and the like.

One of the objects thereof is to provide a simple and practical heater adapted for convenient use in emergencies as in the case .of a train becoming snow-bound or otherwise stalled.

Another object is to provide a car .heatcr of this general naturewhich -.can be conveniently stored on a passenger car and which may be quickly and securely assembled to perform its functions when necessaryl Another object is to provide aheater of this type which is compact and durable and which will prove eflicientand practicable in service.

Other objects will be in :partobvious and in part pointed outhereinafter.

Ihe invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in .the construction bra ska, ful Improvements 1n hereinafter set forth, and the scope of the application of which willbe indicated in the following claims.

In the accompanying drawings, in which is shown one of various possible embodi ments of the invention, Figure 1 is a side elevation of the heater in its assembled position within a car, the positions of the parts when stored being indicated in dottedlines; Fig. 2 is an end view of one of theseats of a car, showing a portion of theheater stored beneath it; Fig.3 is a side elevation of the base of the heater, the ash pit door being removed; Fig. i is aplan view ofFig.-3, parts being broken away for the-sake of clearness; Fig. 5 is a side elevationof the body of the heater, theifire-box'door being removed; parts being shown in-section. Fig. 6 is an elevation of the smokepipe, parts being shown in'section; Fig.'7 is a sectional v1ewtaken on'a line 00-00 ofFig. 5;

Fig. 8 is a vertical sectional view through --a'-floor plateand a portion of the base of the heater showing the mode of; attachment of the heater to the floor. "Fig. 9 is a front elevation of one ofthe heater doors, parts being brokenaway for the sake of clearnessyFigh lO is ;a sectional view taken on the linegg wof Fig. 9.

In order to renler more readily and fully understood certain obj ects of this invention, it may here be noted that in the .use of the ordinary system ofsteam heating as applied to railroadtrains, if a car is cut off fromthertrain, means independent of the locomotivermust be employed for heating the car, if it is desired to maintain it at a normal temperature. Also it may happen that in severe weather there may not be suiticient steam to heat the car comfortably, in which instance other means should be at hand to accomplish this object. In either of theabove or other emergencies it is desirable to .have efficient heating means without an undue occupation of. space.

The above and other objects are attained by meanszof apparatus of the nature hereinafter described.

Referring now to the. drawings, 1 ,indicates the base portion of the .heater compris- 111g an-ash-pit 2 having a bottom 3 below which theiwalls of the base extend a suitable distance in order to provide a space between the bottom of the ash-pit and .theffloor of the car. Openings 4: are formed in the portion of the wall-which extends .below the ash-pitibottom inorder to provide a circulation of air-beneath the same for preventing over-heating of the floor. One or more openings 5 are provided to receive the fastening means by which the heateris secured to the floor as hereinafter described.

An opening 6 11s provided which is adapted to be closedby adoor as hereinafter de- -scribed,;-and through which the ashes may be removed in the usual manner. A grate 7 is positionedin thevupper portion of the base 1 which maybe of any suitable construction that. shown being provided with trunnions 8 placed eccentrically with respect to the diameter of the grate and supported in bearings 9 formed in the base. One of the trunnions isprovided-with a squared extension 10 adapted tofreceive a shaker in the I usual manner. Inorder to hold the grate normally in a horizontal position a lug 11 is provided with the upper surface of which the grate isadapted to engage, as shown in Fig. 3. Adjacent its upper end the base is provided with a shoulder 12 with which the lower end of the body portion 13 of the heater is adapted to engage. Upon base 1 are lugs 14; adapted to engage slots 15 formed in the body portion, thus providing a joint of the bayonet type. The body por tion 13 is cut away as at 16 to form a fuel opening closed by a door, as hereafter described. Handles 17 are preferably secured to the body portion in order to enable the same to be easily handled and carried about. At its upper end the body portion is provided with a smoke opening 18, preferably surrounded by a flange 19 which may be secured thereto in any suitable manner as for example by rivets, as shown in Fig. 5. A damper 2O registers with the smoke opening 18 and is mounted upon a damper-rod 21, the ends of which extend through the flange 19, and a collar 22, also mounted upon the damper-rod, surrounds the flange and is spaced therefrom for a purpose hereinafter described. In assembling these parts, the body portion 13 is so positioned as to permit the lugs 14 upon the base portion 1 to enter the vertical portion of the slots 15, after which the body portion is turned slightly to cause the lugs to engage the inner ends of the horizontal portions of the slots, thereby securely locking the parts in position.

An adjustable smoke pipe 23 is formed of a plurality of sections adapted to telescope within one another, as indicated in Fig. 6, and the lower end of the pipe is provided with a slot 24- adapted to engage and interlock with the damper-rod 21 when this end of the pipe is inserted between the flange 19 and the collar 22. Adjacent its other end the pipe is provided with a flange 25 preferably in the form of a ring, which may be riveted or otherwise secured to the pipe, and which, when the pipe is placed in position, registers with a perforated plate 26 secured at a suitable place within the car, as for example upon its ceiling, from which it is preferably spaced by spacing members 27 in order to prevent the ceiling from becoming over-heated. The upper end of the smoke pipe projects through the perforation in the plate and through a suitable opening in the ceiling of the car which opening is protected by a hood 28 of any usual construction as is common in devices of this character.

The telescopic construction of the smoke pipe enables it to be accurately adapted in length to the height of the vehicle, or the distance between the top of the stove and the smoke pipe opening, and further permits the pipe to be contracted or shortened, and placed within the stove body when the stove is dismantled for storing.

Referring now to Figs. 9 and 10, in which one of the heater doors is shown, 29 indicates the door, which is hinged to a doorframe 30, riveted or otherwise secured to the in the usual manner. In order to regulate the amount of air which passes through the draft openings, a draft-plate 33 is provided which is mounted upon a pin 34, the inner end of which is threaded and engages a threaded perforation in the door. outer end of the pin 34, which extends through the draft-plate, a handle 35 may be secured in any desired manner. From the above description it will be understood that by rotating the handle the draft-plate may be caused to move away or toward the door, depending on the direction of rotation of the handle, thus forming a practical and accurate means of regulating the amount of air which flows through the draft openings 32 in the door. A latch is provided whereby the door may be maintained in its closed position, the handle 36 of which is preferably of the same size and shape as the handle of the draft-plate whereby they are interchangeable.

For enabling the heater to be rigidly secured to the floor of the car when in use, one or more floor plates 37 are provided, each of which comprises an apertured upper portion 38 and a downwardly extending portion 39, provided with a threaded opening 40 registering with the aperture in the upper portion, the downwardly extending portion being preferably inclined as clearly shown in Fig. 8. The floor plates are preferably positioned between adjacent car-seats and secured to the floor bymeans of screws tak ing through opening 40, and are preferably so arranged that the upper surfaces are flush with the car flooring.

The operation and use of the device is as follows: lVhen it is desired to use the heater, the base portion 1 is placed in position upon the floor of the car with the openings 5 formed therein registering with the aperture formed in the floor plates 37 and suitable fastening means such as set-screws are inserted in the registering openings and engage the threaded portion 4-0 of the floor plates thereby securely holding the base in position. The body portion is then placed in position with its slots 15 engaging the lugs 14, on the base portion, as above described. The smoke pipe 23 is then secured to the body portion 13, as above described, with which it is interlocked through the agency of the slots 24, which, as above described, engage with the damper-rod. The upper portion of the smoke pipe is then car To the ried upward to pass through the openings in the plate 26 and car roof with the flange 25 engaging the plate 26 to which it is secured in any suitable manner as by means of one or more set-screws 43 passing through and engaging threaded openings in the flange and plate, as indicated in Fig. 1. The heater is now in its assembled position and may be operated in the usual manner. When it is desired to remove the same, it is merely necessary to reverse the operations above described, after which the parts may be stored.

away ready for future use.

For storing the various parts, there are provided a plurality of receptacles 44, preferably of metal, located beneath the car seats and supported upon the car flooring, within which the parts are adapted to be placed, as indicated in dotted lines in Fig. 1. There are preferably two of these receptacles one of which is adapted to hold the base portion 1 and the other of which is adapted to hold the body portion 13 within which the stovepipe 23 may be inserted in its telescoped condition. Suitable covers 45 may be provided for the receptacles, having handles 46 secured thereto, by means of which they may be removed when it is desired to remove or store the heater portions. The separable stove body permits the use of a stove of adequate dimensions, yet enables the storing or housing of the same when not in use in space beneath the seats of the car or vehicle, which space has no other use.

It will thus be seen that there is provided apparatus of compact construction by means of which the objects of this invention are attained. The parts are simple and inexpensive and may be quickly and readily assembled or disassembled. While there is shown a heater adapted to use coal, it will, of course, be understood that a liquid fuel burning heater might be constructed in such manner as to embody certain features of the invention.

It will be noted upon reference to Figs. 1 and 3 that the openings 5 which receive the fastening screws for securing the base to the floor of the car, are arranged within the diameter of the stove, the lower part of the base being somewhat contracted to permit this to be done. While not essential, this is advantageous in that it avoids any projecti on which might trip occupants of the vehicle or be in tile way.

In Fig. 6 the smoke-pipe sections are shown with stops to limit the relative movement of said sections, a precaution which is advisable where more than two sections of pipe are employed, to guard against the possible separation of the sections through jarring or vibration. The plate or collar 25 secured to the upper section of the pipe limits the projection of said section into the hood or above the car roof, yet insures its the pipe might be so far projecting sufficiently above the roof. Without this, and where as will usually be the case, a hood is employed, theupper end of projected'into the hood as materially to interfere with the draft.

These minor details hence contribute to the proper adjustment and maintenance of relation between parts, and insure satisfactory operation.

It is obvious that many modifications are possible in the details ofthe structure above described and we do not confine ourselves to the particular embodiments above described.
